Homemade water cooling reservoir second attempt once I bought a drillbit set.

I was actually thinking of measuring how effective Mountain Dew is at cooling a CPU.

The price of running a l33t haxor battlestation is, a weekly flush of fresh Mountain Dew!

And since my actual degree (as opposed to what I get paid for!) is in mechanical engineering, if I couldn't solve a system of pump/radiator/etc selection, as well as lubricant compatibility with seals, basically, I never should have graduated.

I could/should probably run less than 50/50 mix since water is a much better heat transfer medium, and there's tons less metal to react with through electrolysis in a CPU cooling setup than a full engine. So I really don't "need" all those additives, nor is my computer ever going to hit -30 F.

Though, I did run it outside once over the winter and had it at ~20 F! The cheap PVC tubing actually goes from flexible, to super stiff (that I dare not bend lest it burst), as it gets that cold. It also had a light layer of frost around it.

But the fittings to go from 1.5" down to 3/8" cost more than the radiator alone and it's so bulky (and my space so limited in my place right now) that I figured I'd reduce the complexity of the project a bit to ensure completion. And I can "upgrade" or build a second one with it later on. Also, the other big issue is that car radiators are super fragile and expect to be protected by the surrounding car. Having one in the open is a recipe for disaster. So when I move up to it, I'll have to build a protective grill/box for it. The "CPU" grade radiators are a little more durable because they know people are stupid and bump into things.

It's also used (in food grade quality) extensively in bars and restaurants in post-mix systems to keep the syrups from separating from the carbonated water. Another use is in e-fluid for the same purpose. Most E-fluid is either 1 50/50 or 30/70 mix of PG and VG (vegetable glycerin).

[when touching] the rate of penetration is so slow that excretion and metabolismpathways are not overwhelmed. Metabolites do not accumulate, therefore, and toxicity does not occur.

I couldn't find any material details on the seals used from random Chinese fitting sellers. But "meh, !@$! it" happened so I winged it. If I was actually experienced in engineering (as opposed to degree), I'd probably be smart enough to tell the material of an o-ring by feeling it, smelling it, etc.

Although, with the bends from gravity/etc, I really could have sprung for the "reinforced PVC" so the tubes wouldn't easily collapse on themselves for future projects. I thought "it's not under vacuum or high pressure so = go cheap" but I didn't think about the small 3/8" tubing collapsing so easily.
